What is circuit board assembly?

Printed circuit board assembly is the process of connecting the
electronic components with the wirings of printed circuit boards. Before
printed circuits became the common component used in electronics, Point
to point construction was used. PCBs can be single sided (one copper
layer),double sided (two copper layers) or multi-layer (outer and inner
layers). FR-4 glass epoxy is the primary insulating substrate.

What is PCB
assembly process?

The
assembly of printed circuit boards is a multiple step process that
includes surface mount technology (SMT) and through hole technology.

What is PCBA manufacturing?

A circuit board prior to assembly of
electronic components is known as PCB.
Once electronic components are soldered, the board is called Printed
Circuit Assembly (PCA) or Printed Circuit Board Assembly (PCBA).

What is a Single Sided PCB?

Single sided PCBs are a type of circuit
boards having components mounted on its one side, whereas the conducting
wires are connected at the other side. Only the desired copper traces or
pathways are left after etching. The conducting layers are typically
made of thin copper foil. Basically, the board is coated with a solder
mask that is in green color. Blue and red are some other colors
available.

Multiple Layer PCBs

Circuit boards that are composed of various layers are known as
multi-layer PCBs. These layers can be either thin etched boards or trace
layers. In both cases, they are bonded with lamination. For lamination,
the internal layers of the PCB are subjected to under extreme
temperature.

Pcb materials comparison

There are many types of dielectrics that can be used to provide
different insulating values as per requirements of the circuit. Unwanted
copper is removed from the substrate after etching leaving only the
desired copper traces or pathways.

You will solder components to the pads on the PCB.It is Location that
components connect to.Pads will connect to traces.Traces are essentially
the wiring of the PCB.

What is a silkscreen on a PCB?

Silkscreen, also known as legend, refers to the text-based,
human-readable information that printed on the surface of a printed
circuit board.

What is “surface mount”?A way of attaching electronic components to a printed circuit
board. Cheaper pcbs with no holes to drill.

Surface Mount vs Through HoleThrough-hole mounting is the process by which component leads are
placed into drilled holes on a bare PCB.Once inserted through the
designated hole in the PCB, the leads are soldered to pads which are
located on the bottom of the board
